STRlKlNG-CLOCK.

$PEGIFIGATION forming part of Letters Patent No. 735,261, dated August4, 1903.

Application filed December 1,1899. Serial No. 738,852. (No model.)

To alt whom it may concern:

Be it known that I, HENRY M. HUNT, a citizen of the United States,residing at Indianapolis, in the county of Marion and State of Indiana,have invented a new and useful Striking- Clock, of which the followingis a specification.

My invention relates to an improvement in mechanical movementsparticularly adapted for use in striking-clocks.

The object of my invention is to produce a simple but effectivemechanical movement by means of which a series of signals may beoperated so as to indicate successive instants of time.

In the drawings I have shown my device as applied to a clock in suchmanner as to indicate each minute by an audible signal which maybereadily distinguished from each preceding and succeeding signal.

The accompanying drawings illustrate my invention. v

Figure 1 is a view of the face of a clock embodying my invention. Fig. 2is a front elevation thereof with the face removed. Fig. 3 is a plan.Fig. 4 is a perspective view of my improved mechanical movement. Fig. 5is a section, on a larger scale, on line 5 5 of Fig. 2. Fig. 6 is anenlarged elevation of a portion of the mechanism. Fig. 7 is an elevationof a modification. Fig. 8 is a section on line 8 8 of Fig. 7. Fig. 9 isan elevation of-a further modification, showing electrical connections.Fig. 10 is a rear view of disk 20. Fig. 11 is a similar view of disk 24.Fig. 12 is a side elevation. Fig. 13 is asectional detail on a linedrawn between teeth 43 and 44 in a plane parallel with Fig. 2.

In the drawings,12 indicates the main shaft, which projects through theface-plate 12 and is provided at its end with a portion 12", to whichthe minute-hand 13 may be secured. Rotatably mounted upon shaft 12 is asleeve 14, on the outer end of which is secured the five-minute hand 15and to the inner end of which is secured a disk 16. Rotatably mountedupon sleeve 14 is a sleeve 17, to the outer end of which is secured anhour-hand 18 and to the inner end of which is secured a disk 19.

Secured to shaft 12, so as to rotate said shaft, is a disk 20, theperiphery of which is center than do pins or teeth 25.

divided into ten equal spaces, Fig. 10. Each of the first nine spaces isprovided with one or more projecting pins 21, which pins are varied innumber in regular succession from 1 to 9. The remaining space on thisdisk is left blank. Projecting from one face of disk 20 are two pins 22,which are fourtenths of a revolution apart. Projecting from the otherface of said disk is a series of ten pins or teeth 23, by means of whichthe said disk may be driven, Figs. 3 and 5. Betatably'moun ted uponshaft 12 is a second plate or disk 24, Figs. 5 and 11, from one face ofwhich projects a series of twelveequally- 'spaced pins or teeth and asingle pin 26,

which pin lies at a greater distance from the Projecting from theopposite face of disk 24 is a series of twelve pins or teeth 27.Projecting from this face of disk 24 is a pin 28, which extends into aslot 29, formed in disk 16, Fig. 5 and dotted in Fig. 4. Slot 29 isconcentric with the shaft 12 and is alittle more than thirty degrees inlength, the arrangement being such that disk 24 may be given areciprocating movement of one-twelfth of a revolution without movingdisk 16.

Rotatabl-y mounted upon sleeve 14 is a disk or plate 30. Projecting fromone face of the disk 30 is a series of twelve pins or teeth 31, andextending from the opposite face is a similar series of pins or teeth32., Projecting from this face of disk 30 is a pin 33, which pinprojects into a slot 34, Fig. 4, similar to slot 29, formed in disk 19.

It will be readily understood that an arm or segment of sufficient widthto carry a slot of a little more than thirty degrees in length might besubstituted for either one of the disks 16'and 19.

The periphery of disk 24 is divided into twelve equal parts, and thefirst two of the portions are left blank, Fig. 11. Projecting from eachof the second two portions is a single pin 35. From each of the thirdpair of portions two pins project, and each of the succeeding pair ofportions is provided with an additional pin, so that each of the lastpair of portions is provided with five pins. The periphery of disk 30 isdivided into twelve equal portions, from each of which projects one ormore pins 36,Fig. 4, the numher of pins in each section varying inregular order from 1 to 12. The several disks and hands operated therebyare driven by means of a suitable spring or other motor 37, controlledby the usual pallet 38 and escapement-wheel 39, which are connected tosaid motor by means of the usual train of gears. Said train of gears,Fig. 12 and dotted in Fig. 2,drives a shaft 40, which in turn by meansof a pair of equal gears 41 and 42 drives a shaft 43 in the oppositedirection. Secured to shaft are two driving-teeth 44 and 45, Fig. 4.Tooth 44 is arranged to engage pins or teeth 27 of disk 24, and tooth 45is arranged to engage pins or teeth 31 of disk 30. Secured to shaft 43are three drivingteeth 46, 47, and 43, Figs. 4, 5, 6, the arrangement ofsaid teeth being such that tooth 46 may engage pins 23 of disk 20, tooth47 may engage pins 27 of disk 24, and tooth 48 may engage pins 31 ofdisk 30. Tooth 45 is arranged slightly in advance of tooth 44, and shaft40 rotates so that said teeth will drive the disks 24 and 30,respectively, backward.

Teeth 46, 47, and 43 are arranged in the order named around shaft 43,which rotates so as to cause said teeth to drive disks 20, 24, and 30,respectively, forward. Mounted in suitable bearings parallel to theseveral shafts already mentioned is a shaft 49, Figs. 3, 4, 6, uponwhich is secured a pair of gears 50 and 50'. Gear 50- is arranged to beengaged by pin 26 of disk 24, and gear 50 is arranged to engage any oneof pins 32 of disk 30 when gear 50 is rotated, and thus drive said diskin a clockwise direction. Revolubly mounted on shaft 49, but secured soas to rotate together, is a pair of gears 51 and 51. Gear 51 is soarranged as to be engaged by either one of pins 22 of disk 20 and gear51 is arranged to engage any one of pins 25 of disk 24. The teeth ofgears 50 and 51 are so spaced that after either has operated to advanceits adjacent disk 30 or 24, respectively, the said disks may be freelyrotated in either direction without engaging the said teeth. The teeth21, 35, and 36 of disks 20, 24, and 30, respectively, may be caused tooperate any one of a number of convenient forms of alarm or signalmechanisms. In Figs. 2, 3, 5, and 6 I have illustrated a form in which Iprovide three bells 52, 53, and 54, the said bells having tones easilydistinguishable one from the other. Bell 52 may be struck by a hammer ofany well-known form, said hammer having an arm 56, the end of which maybe caused to lie in the path of movement of pins 36. Bell 53 may bestruck by a similar hammer 57, having an operating-arm 58, which may bemade to lie in the path of movement of pins 35. A similar hammer 59 isarranged to strike bell 54, and the end of its operatingarm may becaused to lie in the path of movement of pins 21. Each of the saidhammers may be drawn down to striking position by a suitable spring orotherwise. As will appear in the description of the operation,

disks 24 and 30 are intermittently oscillated in both directions, and inorder to prevent the pins 35 and 36 from engaging arms 58 and 56,respectively, during the forward oscillation of said disks I mount uponshaft 43 a cam 61, Figs. 6, 9, which is adapted to engage an arm 62,which in turn engages arms 63, secured to hammers 55 and 57, so thatduring that portion of the revolution of shaft 43 which coincides withthe forward oscillation of said disks arms 56 and 58 are lifted out'ofthe paths of movement of pins 36 and 35, respectiveiy. The cam 61 andconnected portions perform a double function. Shaft 43 is so connectedto the train of driving-gears as to make a complete revolution eachminute, and said shaft carries upon its face end a seconds-hand 64,Figs. 1,12. Cam 61 is provided with a sudden drop 65, Fig. 6, which isso arranged that as soon as the disks 24 and 30 have completed theirreverse or clockwise oscillation arm 62 is withdrawn from arms 63 withsufficient suddenness to cause hammers 55 and 57 to strikesimultaneously their respective bells 52 and 53, thus causing once eachminute an easily-distinguishable signal, which I will hereinafterdesignate as the counting-signal. At the same time arms 56 and drop downinto paths of movement of the pins 36 and 35, respectively.

The operation is as follows: Starting with the hands in the positionshown in Fig. l, which indicates twenty minutes past eight, the partswill then be in the position shown in Fig. 6. Just as the seconds-hand64 is brought to the position shown in Fig. 1 the mechanism has operatedso as to strike eight, two, or 8.20. An advance of shaft 43 aboutone-half of a revolution, or thirty seconds, then brings shoulder 65 ofcam 61 beneath arm 62, and thus allows hammers 55 and 57 to dropsimultaneously into engagement with bells 52 and 53, thus sounding thecounting-signal and indicating that the parts are in position for thelistener to begin the count. At this time disk 30 is in such positionthat the group of pins 36 immediately to the right of arm 56 is composedof eight pins, disk 24 is in such position that the first group of twopins 35 lies to the right of arm 58, and disk 20 is in such positionthat the first group of pins 21 (composed of one pin) lies to the leftof arm 60. Immediately following the simultaneous dropping of hammers 55and 57 tooth 45 comes into engagement with one of pins 31 of disk 30 anddrives said disk backward through one-twelfth of a revolution, thusdrawing the adjacent pins 36 beneath arm 56 and causing hammer 55 tostrike bell 52 eight times, and thereby indicating the hour. A continuedadvancement of shaft 43 brings tooth 44 into engagement with pins 27 ofdisk 24, the said disk being driven backward through one-twelfth of arevolution and drawing the two adjacent pins 35 beneath arm 58, so as tocause hammer 57 to strike bell 53 two times, and thereby indieating thenumber of ten-minute groups. A continued advancement of the shaft 43brings tooth 46 into engagement with one of pins 23 of disk 20 anddrives disk 20 forward through one-tenth of a revolution, so as to drawpin 21 beneath arm 60 and cause hammer 59 to strike bell 54 one time,thus indicating the minutes past the ten-minute period indicated by thebell 53. At the same time hand 13 is moved forward to the one minutemark and the group of two pins 21 is brought to the left of arm 60., Atthis time the seconds-hand again reaches its starting-point. As shaft 43advances to indicate the first part of the following minute tooth 47 isbrought into engagement with one of pins 27 and oscil-' lates disk 24forward through one-twelfth of a revolution, thus returning the samegroup of pins 35 to the right of arm 58. Immediately following theaction of tooth 47 tooth 48 is brought into engagement with one of pins31 of disk 30 and drives said disk in a return or forward direction, soas to return the eighth group of pins 36 to the right of arm'56.

When the parts have reached the positions just described, the teeth 44,45, 46, 47, and 48 are in such positions that the several disks may befreely rotated in either direction. The teeth of gears 51, 50, and alsolie insuch position that they will not be engaged by any of the pins oftheadjacent disks, so that by lifting hammers and 57 and by any suitablemeans, such as aseries of fingers 66, the hands 13, 15, and 18 may beset at any desired point. Up to this point the oscillation of disks 24and 30 have produced no efiect upon the hands 15 and 18, respectively,because pins 28 and 33 have been merely oscillated from one end to theother of their respective slots 29 and 34 in disks 16 and19,respectively. The operation just described is repeated each minutefor four minutes, the disks 24 and 30 being oscillated first backwardand then forward through one-twelfth of a revolution and disk 20 beingadvanced one-tenth of a revolution each minute. When the hands stand soas to indicate 8.24 and thirty seconds,the countingsignal has beensounded by the simultaneous action of hammers 55 and 57, the eighthgroup of pins 36 lies to the right of arm 56, the first group of two ofpins 35 lies to the right of arm 58, the group of five pins 21 lies tothe left of arm 60, and one of pins 22 is just coming into engagementwith one of the teeth of gear 51. An advancement of shaft 43 from thisposition brings tooth 45 into engagement with one of pins 31, so as todrive disk 30 backward and cause hammer 55 to strike bell 52 eighttimes. Tooth 44 then engages one ofpins 27 and drives disk 24 backward,so as to cause hammer 57 to strike bell 53 two times. In this positionpins 28 and 33 of disks 24 and 30, respectively, lie at the extreme leftor rear ends of slots 29 and 34, respectively, of the disks 16 and 19.Tooth 46 then comes into engagement with one of pins 23 of disk 20 anddrives said disk forward, so as to cause hammer 59 to strike bell 54five times. At the same time pin 22 comes into engagement with one ofthe teeth of gear 51 and causes saidgear and .gear 51 to rotate, thusbringing one of the teeth of gear 51 into engagement with one of pins 25of disk 24, so as to advance said disk through one-twelfth of arevolution forward. This advancement of disk 24 by gear 51 so shifts thedisk 24 that when tooth 47 comes into position to engage one of pins 27the disk is one-twelfth of a revolution in advance of what it would havebeen had gear5l' remained stationary, and pin 28 lies at the extremeright or forward end of the slot 29 of disk 16. A continued advancementof shaft 43 causes tooth 47 to engage the proper pin 27, so as toadvance disk 24 forward through another one-twelfth of a revolution.This movement of disk 24 causes pin 28 to drive disk 16 throughone-twelfth of a revolution,

thus advancing hand 15 from IV to V on the face of the clock,thisadditional movement of disk 24 bringing the second group of two pins 35to the right ofarm 58. Disk 30 is then returned forward by tooth 48through onetwelfth of a revolution, and the parts are in position tostrike eight, two, six, or 8.26. The operation previously described isrepeated each minute until 8.28 and thirty seconds, at which time hand18 still remains opposite VIII, hand 15 stands at V, hand 13 stands at8, and hand 64 stands at 30. At this ti me the counting-signal is againgiven and the eighth group of pins 36 lies to the right of arm 56, thesecond group of two pins 35 lies to the right of arm 58, the group ofnine pins 21 lies to the left of arm 60, and the second one of pins 22is coming into engagement with one of teeth on gear 51. As the severalparts are ad vancing in the manner already described and cause theseveral bells to sound the disk 24 is again advanced onetwelfth of arevolution by the action of gears 51 and 51, and the action of tooth 47on said disk advances hand 15 to VI. The operations already describedare continued in proper sequence each minute, the disk 20 being advancedforward one-tenth of a revolution each minute and disk 24 being advancedforward one-twelfth of a revolution twice in every ten minutes, thismovement being addition to the backward and forward oscillations ofone-twelfth of a revolution each min-v ute. At 8.58 and thirty secondswe have the following conditions: Hand 18 remains opposite VIII, withdisk 30, so that the eighth group of pins 36 lies to the right of arm 56and pin 33 at the forward end ofslot 34, hand 15 stands opposite XI, andthe second group of five of pins 35 lies to the right of arm 58, withpin 28 at the forward end of slot 29, and the group of nine pins 21 ofdisk 20 lies to the left of arm 60. At this time one of pins 22 iscoming into engagement with one of the teeth of gear 51. When the partshave reached these positions, the counting-signal has just sounded, disk30 is driven backward through end of slot 29. ward one-tenth of arevolution, thus striking one-twelfth of a revolution, thus strikingbell 52 eight times, and pin 33 lies at the rear end of the slot 34.Disk 24 is then driven backward one-twelfth of a revolution, thusstriking bell 53 five times and bringing pin 28 to the rear Disk 20 isthen driven forbell 54 nine times. The advancement of disk 20 at thispoint causes one of pins 22 to rotate gears 51 and 51, the gear 51 thusoperating to advance disk 24 forward one-twelfth of a revolution, so asto bring pin 28 to the forward end of slot 29. As soon as this occurstooth 47 engages one of pins 27 and continues the advance of disk 24through another one-twelfth of a revolution, said advance moving hand 15to XII. During this last forward advancement of disk 24 pin 26 thereofdrives gears 50 and 50 so as to cause gear 50 to engage one of pins 32and advance disk 30 forward one-twelfth of a revolution, thus bringingpin 33 thereof to the forward end of slot 34. As soon as thisadvancement of disk 30 is completed tooth 48 comes into engagement withone of pins 31 thereof and continues the forward advancement of head 30another one-twelfth of a revolution, thus bringing the ninth group ofpins 36 to the right of arm 56 and hand 18 opposite IX. At 8:59 andthirty seconds, hand 18 is opposite IX, the ninth group of pins 36 liesto the right of arm 56, and pin 33 lies at the forward end of slot 34 5hand 15 stands opposite XII, the first blank space of the periphery ofdisk 24 stands to the right of arm 58, and pin 28 lies at the forwardend of slot 29; hand 13 stands opposite 9, and the blank portion of theperiphery of disk 20 lies immediately to the left of arm 60. Thecountingsignal is then given, after which disk 30 is driven backwardone-twelfth of a revolution, so as to strike bell 52 nine times. Disk 24is driven backward to carry the first blank portion of the periphery ofdisk 24 beneath arm 58, so that bell 52 is not sounded, and the blankportion of the periphery of disk 20 is driven forward beneath arm andbell 54 is not sounded. Each succeeding minute is indicated, as alreadydescribed.

It will be readily understood that many different forms of soundingmechanisms or signals may be used in connection with and operated by themechanical movement just described. In Figs. 7 and 8 I haveshown aconstruction in which I provide a series of vibrating tongues 68, 69,and 70, the said tongues being in positions to be engaged by theprojecting pins 36, 35, and 21, respectively. In order to withdrawtongues 68 and 69 during the return oscillation of disks 24 and 30, thesaid tongues may be mounted upon a pivoted frame 71, which may be swungat the proper time once each minute by means of an arm 72, operated uponby cam 61.

The mechanical movement just described may be also used to operateelectrically a purnber of signals which may be placed at widelyseparated points. A construction such as is shown in Fig. 9 would beapplicable in this case. I provide a series of terminals 73, 74, 75, and76, which are insulated from the frame of the movement and which arearranged to be engaged by pins 36, 35, and 21, respectively. For reasonsalready stated terminals 73 and 74 should be intermittently withdrawnfrom the paths of movement of the pins 36 and 35. Said terminals maytherefore be carried by a pivoted frame 77, which may be properly swungby a lever 78, acted upon by cam 61.

Suitable holding means may be provided to prevent the parts frombecoming accidentally misplaced; but for the sake of clearness suchmeans have been omitted from the drawings, as any desired form may beused.

It will be readily understood that disks 20, 24, and 30 may be providedwith any desirable forms of operating means other and equivalent to theseveral sets of pins mentioned without departing from my invention.
